Abicycle traveled 150 meters west from point a to point b. then it took the same route and came back to point a. it took a total of 2 minutes for the bicycle to return to point a. what is the average speed and average velocity of the bicycle? a. the average speed is 2.5 meters/second, and the average velocity is 2.5 meters/second east. b. the average speed is 0 meters/second, and the average velocity is 2.5 meters/second east. c. the average speed and average velocity are both 0 meters/second. d. the average speed is 2.5 meters/second, and the average velocity is 0 meters/second.

Answer

D. The average speed is 2.5 meters/second, and the average velocity is 0 meters/second.

The difference between speed and velocity is that, speed is a scalar quantity while velocity is a vector quantity.

Average speed = total distance/Total time

                          = (150 + 150) / (2×60)

                          = 300/120

                           = 2.5 m/s

Average velocity = Total displacement/ Total time

                             = (150 + -150) / (2 × 60)

                            = 0/120

                            = 0 m/s  

real, smaller and upside-down.   so the answer should be b.
